This question is about placement of encryption function and key exchange  c. Discuss Diffie-Hellman key exchange protocols to enable two users to securely exchange a key that can be used for subsequent encryption of messages. d. In Diffie-Hellman key exchange is based on the use of the prime number q = 353 and a primitive root of 353, in this case α = 3. A and B select secret keys XA = 97 and XB = 233, respectively. Use this information to compute public key for both sender A and Receiver B. Once the public key is calculated then compute a common secrete key.
